For custom layouts, did I understand the “FC Switch Definitions” correctly? There are 24 definitions you can set up *per preset* - not 24 globally? So you can essentially have totally custom layouts for each preset if you wanted, by taking one layout and modifying it in each preset with whatever specific things you want to control...? The manual says 'for “that one song” which needs to do something unusual' but I'm thinking you can use this to essentially have anything anywhere you want it in each preset, AX8-style.
